SKYRC LiPoPal is a simply used battery checker and self voltage balancer. When we are flying or running outside, it is difficult to know the remaining capacity of the battery. With this tiny LiPoPal we could check the voltage of each cell and the remaining capacity in percentage at anytime and anywhere. As we know, if each cell of the battery pack is balanced, the battery performance will be much better and the cycle life will be longer. But sometimes, we may dont have time or tool to balance the battery cell. With this small kit, when it detects the pack is not balanced, it will start work to balance the pack cell at once. There are two functions of this compact device:Battery Checker - The LiPoPal can check the voltage of each cell of a lithium battery pack and remaining capacity in percentage %.Self Voltage Balancer - This program can equalize the individual voltages to their lowest one. Balance operation automatically starts about 5 seconds after the battery pack is connected. Whe
